Aim: This research aimed to investigate the differences in the sealing capability of propolis extracts and Ca(OH) on dentin surfaces.
Materials And Methods: Eighteen mandible incisors of Wistar rats were prepared at a depth of 0.5 mm after which they were randomly divided into 3 groups (n=6) including control (C), pulp-capped with Ca(OH) group (P1), and indirect pulp-capped with propolis extract group (P2).
